OEM 2006 Toyota Tacoma Air Bag

2006 Toyota Tacoma Parts Questions & Experts Answers

• Q: What precautions should be taken when servicing a vehicle equipped with SRS to prevent unexpected Air Bag deployment on 2006 Toyota Tacoma?

  A: The vehicle contains SRS technology with its components including driver Air Bags and front passenger Air Bags and side Air Bags and curtain shield Air Bags. It requires a proper servicing order to safeguard against unintentional Air Bag activation during maintenance because this could result in severe accidents. When servicing vehicles always wait for 90 seconds or longer after toggling the ignition to LOCK and disengaging the negative (-) terminal from the battery because the system has onboard Back Up power. All technicians should prevent the Steering pad along with the front panel passenger Air Bag assembly, Center Air Bag sensor assembly, front Air Bag sensor, front seat side Air Bag assembly, side Air Bag sensor, curtain shield Air Bag assembly, rear Air Bag sensor, seat position sensor, and occupant classification ECU from direct exposure to hot air or fire during servicing. The occupant classification ECU needs initialization whenever the ECU is replaced or accessories are installed or the passenger seat is removed and reinstalled when the passenger Air Bag ON/OFF indicator lights up (OFF) or after an accident repair of the vehicle. The inspection of DTCs must be performed before disconnecting the battery since these diagnostic codes help with SRS troubleshooting. Examine every single relevant component in all situations that amount to minor vehicle collisions even when the SRS fails to activate its safety features. The Air Bag sensor should get removed before starting any repair process that could damage it and technicians must exclusively work with new SRS components from different sources. All repair or disassembly of SRS components should be avoided because reusable parts require new components and components that experience any drops or exhibit damage need immediate replacement. For electrical circuit troubleshooting use a volt/ohmmeter device that features minimum impedance of 10 kOhms/V while following the instructions from information labels on SRS components. Check the SRS warning light after finishing SRS work yet remember connecting or disconnecting the negative (-) terminal cable will reset memory causing data to disappear. Thus document all system contents before beginning work and restore them afterward. Service precautions for mobile communication systems must be followed when they exist on the vehicle. Before investigating wire harnesses it is important to detach the Center Air Bag Sensor assembly, Front Air Bag Sensor LH, Front Air Bag Sensor RH, Side Air Bag Sensor LH, Side Air Bag Sensor RH, Rear Air Bag Sensor LH, and Rear Air Bag Sensor RH to avoid unexpected Air Bag deployment. Sensors need a minimum 90-second waiting period without the negative (-) terminal cable present when service includes Air Bag sensors or side and curtain shield Air Bags in front/rear doors. The installation procedures require Air Bag sensors to be present in the vehicle during connector work while eliminating from use any sensors that experienced falls. The compressor protection control system can disengage the clutch when the engine operates at less than 2000 rpm for at least 1 minute after negative battery terminal cable reconnection. This process should be avoided for Air Bag sensors and normal operation should be maintained.
